If you find your USB transfer speed slow, there are several ways you can fix the issue. Most of the time the error can be rectified with the Windows’ built-in tools itself. However, if the problem is severe, you need a third-party app that has been designed specifically for the purpose. That said, here you will learn about a couple of methods to improve the performance, typically the transfer speed, of your USB drive.


Part 1: Why Do USB Drives Transfer Data So Slowly?

To begin with, this is a relative question. If you bought a new piece and notice USB transfer speed very slow Windows 10 or Mac, the device itself might not be faulty. To confirm, you can check the version of the drive you received, i.e. if it is 2.0 or 3.0. The information can be found on the body of the drive or on the cover it was shipped in.

For reference, the transfer rate of USB 2.0 is 480Mbps (Megabits per second), whereas a USB 3.0 can send or receive data as fast as up to 5Gbps (Gigabits per second). There are many tools such as USB Flash Benchmark, SpeedOut, USBDeview, etc. that allow you to check the speed of your USB for free.

Therefore, before doubting the integrity of your flash drive, it is advisable to check if the speed you are getting is normal. In case you notice significant lethargy in the functioning of the device as compared to what you should get or were getting earlier, there could be a couple of reasons for that including:

Not particularly hardware, but the USB port might have malfunctioned or may have an obsolete driver. Isolating the issue post proper diagnosis, and then addressing it should fix the problem.

Since the transfers may take place from USB to your PC or vice versa, any issue with the source device may hinder the performance. Such problems may include bad clusters, virus infections, bad sectors, improper or incorrectly managed file systems, fragmented files, etc.

As it is with the source device, the target device could be faulty as well. In case your USB is the target device and it shows poor performance, it may have an incompatible file system, faulty file allocation table (FAT), or bad sectors. Detecting the problem(s), and fixing it/them should bring the device back to normal.

Depending on the cause of the trouble your flash drive has, the solutions may vary. Some of the most effective methods to resolve the issue include:

Method 1: Change the Port – The first thing you can try is, plug the drive to a different port. You can learn more about it here.

Method 2: Convert USB 3.0 from FAT32 to NTFS – This method requires you to recover your data from a faulty USB, save it to a separate storage media, and then use the procedure explained in Method 3 to convert FAT32 to NTFS to fix the issue with the drive. The detailed process to do this can be found here.

Method 3: Formatting the Drive – In this scenario, this method works in correlation with the previous one. Although not recommended, this solution helps most of the time. The process of formatting a USB drive can be found here.

Method 4: Update Drivers – As discussed above, obsolete drivers can also be the cause of poor USB performance, and updating them could do the trick. Detailed instructions can be found here.

Method 5: Optimization – Optimizing the performance of your USB stick is yet another way to resolve the problem with the least intervention. You can get all the details here.

Method 6: Check BIOS/Firmware for 3.0 – Sometimes the USB 3.0 option gets disabled in BIOS/UEFI. Possible reasons could be BIOS upgrades, unexpected shutdown, corrupt CMOS settings, weak CMOS battery, etc. The instructions on how to check the Firmware/BIOS and enable 3.0 can be found here.


Part 2: 6 Effective Methods to Improve USB Transfer Speed

Once you have noticed that the USB transfer speed slows on PC, it is now time to dive in and try all the possible solutions that could fix the problem. All those six troubleshooting methods are explained below in detail:

Method 1: Change the USB Port

If there was a malfunction on the port your USB is connected to, it is a good idea to disconnect the device from there, and plug it into a different port. In case you are using a desktop computer, it is advisable to connect the flash drive to any of the rear ports of the system case (usually referred to as the CPU).

If the computer is able to detect the USB, you can continue using it normally, and the issue with the culprit port is likely to be fixed automatically upon the next Windows restart.

Method 2: Convert USB 3.0 from FAT32 to NTFS

This method works in correlation with the next one, Method 3, wherein you first follow the steps given here to recover your lost files from the USB, and then move on to the next procedure to convert the drive to NTFS in order to make it secure so it doesn’t come up with any security issue again.

When talking about recovering the lost files, even though there are several data recovery tools available in the market today, the most trusted one that also simplifies the entire process is Wondershare Recoverit.

The software works in real-time where it automatically detects any new drive that is connected to the computer and then allows you to scan it for the deleted or lost files.

This method requires you to enter into your motherboard’s BIOS or UEFI (Unified Extensible Firmware Interface). Depending on the manufacturer and the architecture of the board, the process of checking for and enabling USB 3.0 may vary. Nevertheless, regardless of the screens and the name of the options that your computer’s BIOS/Firmware has, the basic principle remains the same. The following instructions explain how to enable USB 3.0 on your computer.

Step 1: Go to the Motherboard’s BIOS/Firmware

Earlier you could enter the BIOS setup by pressing the Del key repeatedly right after powering on your computer. However, the new PCs have different keys to take you there. For some it is F12, for others it is F10, and for a few of them, it is even the Esc key. Therefore, you may need to check the manufacturer’s website or your PC’s Owner’s Manual to find out the correct key or combination of keys to get to the Firmware or BIOS window of the motherboard.

Step 2: Enable USB 3.0

Use the left and right arrow keys on your keyboard to get to the Advanced tab, use the up and down keys to select USB Configuration (or something similar to this), and press Enter. On the next screen, use the arrow keys again to select USB 3.0 (or 2.0) Support, press Enter, select Enabled or USB 3.0 (whatever option is available to enable USB 3.0), and press Enter again.

Step 3: Save the Changes and Restart

Press F10 and then press Enter to save the settings and restart the PC. In some computers, you may need to go to the Exit tab and pick Save and Restart (or any other similar option) to exit the setup saving the changes.

Conclusion

If you notice USB copying speed slow, before starting with the troubleshooting, scan the drive with a strong antivirus program and see if the performance improves after that. If the issue persists, any of the solutions discussed above would help. However, if you are looking for an easy way to rectify the problem, you can jump right on to Method 2 to use an efficient tool, Wondershare Recoverit that is worth a try.
